Exam 1 v Page 2 of 5 . Sorting Number: 1) Three points (A, B, and C) are shown in the figure. The coordinates of the three points are: A: (X, Y, Z) = (0.0, 10 in, 0.0)
B: (X, Y, Z) = (0.0, 3 in, 12 in)
C: (X, Y, Z) = (8 in, 4 in , 5 in) Find the following. Express your result in terms of unit component vectors:
" a) FAC (the positioh vector from A to C) b) the projection of FAC onto the line defined by points A and B c) If a force F = (16N)}t is applied at point A, resolve this force into components parallel and
perpendicular to the line defined by points A and B. » ’5: 795“ my“, 5°12

Exam 1 ; v Page 4 of 5 . Sorting Number: 2) Consider the system below with two linkages joined at point A with a pin as shown. Force F is
applied at point A. Force F is purely horizontal with a magnitude of 500 lb and angle oc = 20°. Find the angel [3 required so that the compdnent of F acting along member AB is 2.8 kN.. ,IB ...
